So if you are putting a new outlet in an old house that used to have non
grounded outlets, what is the acceptable method for hooking up the new
grounded outlet as you cannot buy the non grounded ones anymore and are not
running new grounded cable.

1. Just Not hook up the ground?

2. Hook up the ground to the neutral ( is this better than 1?)

On a hydro pole, there are always 3 wires...at least in Canada. The 3rd

wire is neutral, going back to the substation, isn't it?

Why is that 3rd wire there if neutral is simply tied to ground at the
panel. This would seem to obviate the need for that 3rd transmission
wire.


I don't know about Canada, but in the U.S....

-For a home there will be 3 wires - two hots and a neutral.
-At the top of the electric pole will be 3 wires - 3 hots - 3 phase.
-Sometimes lower on the pole will be 3 wires - two hots and a neutral.
-For businesses there may be 4 wires - 3 hots (3 phase) and a neutral.
Then
this gets *very* complicated as to what the 4 wires are for depending on
the
transformer and how it is wired. See following...

3 phase makes large electric motors run more efficiently basically. Homes
are usually connected to single phase.
